Solder-on terminals for direct connection to Carrera terminal track (set of 3). These terminals let you replace other types of connectors (e.g. alligator clips) on your controllers with connectors that can be connected directly to Carrera power bases.
Carrera power bases are wired for negative polarity. If you plan to use these connectors with a resistor-based controller, polarity will not be an issue. If you plan to use these connetors, the controller must be designed for used with negative polarity wiring OR the controller must have a dual-polarity feature.
